Mediterranean Gull
One of only two Mediterranean gulls amongst hundreds of black-headed, lesser black-backed and yellow-legged gulls on the salt pans at Olhão. I did read that the Med gulls were winter migrants so maybe even these will be gone soon.
ID in summer plumage is straightforward. The head cap is black not dark brown and covers the back of the neck. There is also no black on the wing tips.
